Drain Flies
Two types of small flies occasionally appear in
kitchen areas. Several species of fruit flies (also known
as pomace or vinegar flies) are common in kitchens. They
are from 1/16-1/8 inch (1-3mm) long, yellowish or
brownish with black markings, and fairly bristly. The
larvae (maggots) develop in decaying vegetable matter,
feeding on the yeast and molds which grow on over-ripe
fruit or vegetables. In the home they are found near
decaying potatoes, fruits and vegetables, flower bulbs,
bread and baked goods containing yeast, beverages (beer,
pop and fruit juices), and vinegar. They are also
occasionally found in the small quantities of milk,
catsup, juice or pop left in empty bottles and in sour
dishcloths and mops. Disposal of infested items is
strongly suggested to eliminate them. A labeled insecticide spray
may be required to eliminate the adults.
A second type of small fly that is frequently
encountered in the kitchen area is the moth (drain) fly.
These flies are 4-5mm (1/16-1/4 inch) long, grayish,
densely hairy and hold their oval wings rooflike over the
abdomen. Their flight is weak but they are very agile
runners. The larvae of these flies develop in sink traps
and other stagnant water. Thus they are common in laundry
tub and basement floor drains, sumps, toilet and shower
drains, as well as the kitchen sink (especially if there
is a garbage disposal). The larvae feed on sewage and
other organic matter that builds up on the inside of
drain pipes. Drain Gel works well in this situation.Never pour a insecticide down the drain! Drains can be treated with Gentrol or Bio-mop or Drain Gel only.
